84489 ÷ 66 
We want to divide 84489 by 66.

Advancing to step 1:
66 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 66

On to step 2:
66 goes into 84 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 66 from 84 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 66

Let's proceed to step 3:
66 goes into 184 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 132 from 184 to get 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 66

Step 4:
66 can be fit into 528 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 528 from 528, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 66

Going ahead to step 5:
If we divide 9 by 66, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 1280.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 6:
90 divided by 66 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1280.1
If we take 66 away from 90, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 66 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1280.13
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1280.136
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 1280.1363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
When dividing 420 by 66, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1280.13636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 1280.136363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
66 goes into 420 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1280.1363636
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
240 divided by 66 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1280.13636363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 1280.13636363 with a balance of 4.2e-08.
